"Looks like having a family who likes the same band can be put into good use sometimes."

Perjuangan seorang Yesung, mencari Appa biologis  bagi janin yang ada dalam rahimnya. Apakah itu Kangin? sang mantan pacarnya atau Cho Kyuhyun? suami yang baru di nikahinya dua bulan belakangan?

It's been three years since Kyuhyun proposed Yumi and now, they are husband and wife and also parents for their 1 years old son, Cho Yu Hyun. How will Kyuhyun manage to take care their baby when Yumi had to go out for the urgent meeting, especially this is the first time he took care of him alone without his wife? Would it be disaster or else?
